Expand description
Per-stream monotonic sequence frontier — durable state for outbound frame stamping and inbound ack tracking.
§Persistence
Each per-stream frontier is persisted under Namespace::Meta with key
"sync.stream_seq:{stream_id:016x}". The 16-byte value encodes
last_assigned || last_acked as two big-endian u64s.
StreamSeqTracker::load restores all entries on startup so the first
outbound frame after a restart continues from where it left off (the
persist-before-send invariant is maintained across process restarts).
